An expression of partial-wave expansion three-baryon interactions in chiral effective field theory is presented. The derivation follows the method by Hebeler et al. [Phys. Rev. C 91, 044001 (2015)], but final more general. That is, a systematic treatment higher-rank spin-momentum structure interaction becomes possible. Using derived formula, $\mathrm{\ensuremath{\Lambda}}$-deuteron folding pote...

Abstract Our study focuses on the $\Lambda$-type P-wave bottom baryon states with spin-parity $J^P=\frac{1}{2}^-$, $\frac{3}{2}^-$. We introduce an explicit between two light quarks in interpolating currents (and are antisymmetric flavor space, therefore leads to name baryon) investigate $\Lambda_b$ and $\Xi_b$ within framework of full QCD sum rules. The predicted masses show that $\Xi_b(6087)$...

Two-particle azimuthal correlations are measured with the ALICE apparatus in pp collisions at $\sqrt{s} = 13$ TeV to explore strangeness- and multiplicity-related effects fragmentation of jets transition regime between bulk hard production, probed condition that a strange meson (K$^{0}_{\rm S}$) or baryon ($\Lambda$) transverse momentum $p_{\rm T} > 3$ GeV/c is produced. Azimuthal kaons $\Lambd...

The increase in yields of light nuclei with charged particle multiplicity, as reported by the ALICE collaboration at CERN p-p and p-Pb collisions LHC energy is investigated thermal hadron resonance gas model. model extended to account for exact baryon number conservation. focus on production protons, deuterons, $^3$He, $^3_\Lambda$H. A very good description proton deuteron obtained a function m...

We test the mutual consistency between baryon acoustic oscillation measurements from eBOSS SDSS final release, as well Pantheon supernova compilation in a model independent fashion using Gaussian process regression. also their joint with $\Lambda$CDM model, fashion. use regression to reconstruct expansion history that is preferred by these two datasets. While this methodology finds no significa...

In the paper, we consider two models in which dark energy is coupled with either dust matter or matter, and discuss conditions that allow more time for structure formation to take place at high redshifts. These are expected have a larger age of universe than $\Lambda$CDM [universe consists cold (CDM) (a cosmological constant, $\Lambda$)], so it can explain redshift gravitationally bound systems...

The nonleptonic two-body ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Lambda}}\ensuremath{\psi}$ decays with $\ensuremath{\psi}=J/\ensuremath{\psi}$ or $\ensuremath{\psi}(2S)$ are investigated based on the perturbative QCD approach. These color-suppressed processes in which nonfactorizable contributions confirmed to be dominant. Angular momentum conservation ...

The semileptonic decays of $\Lambda_{b}\to\Lambda_{c}^{(*)}\ell\nu_\ell$ and $\Lambda_{c}\to\Lambda^{(*)}\ell\nu_\ell$ are studied in the light-front quark model this work. Instead quark-diquark approximation, we use three-body wave functions obtained by baryon spectroscopy. ground states $(1/2^{+})$, $\lambda$-mode orbital excited $(1/2^{-})$, first radial $(1/2^{+})$ $\Lambda_{(c)}^{(*)}$ con...
